Prevent possible crash on pages with iframes.

In some cases, setupFrame() has not been invoked (due to the queued
signal-slot connection) after the frame is destroyed and thus leads
to the crash. We prevent this from happening by making sure it is a
direct connection instead and therefore setupFrame() will be executed
as soon as possible.

Adding the whole 'bin' folder to '.gitignore'

On Windows, there are 3 files produced in the 'bin' folder and none of them should be checked in.
Updated help output to prefer true/false to yes/no

Similarly, I updated the API Reference too:
https://github.com/ariya/phantomjs/wiki/API-Reference/7cddd19676a917535b74d386c3974da00fbbe793

This arguably makes more sense to PhantomJS's typical audience of web developers.

Make require.stub() optionally accept a factory function

require.stub() can now accept a factory function instead of an object
so that stubbed modules are initialized lazily:

require.stub('zlib', function() {
    // initialized once, when zlib first required
    return {
        createGzip: function() { ... }
    };
});

Renew the weather example with OpenWeatherMap service.

Google "secret" Weather API is shutdown. Let's use the crowd-sourced
OpenWeatherMap to supply the weather data (albeit there is no forecast
available).
